THE CUTTING OF BREAD
When eating bread during the week, a cut should be make in the loaf before making the bracha. This is so that there will not be too much of a separation between making the bracha and then cutting the bread. However, a person should be careful not to cut so much that any bread falls off. On Shabbos, he should not cut the bread before making the bracha, but he should just make a slight mark with his knife in the challah. After making the bracha, he should cut the challah at this mark. On Shabbos, everyone should be given a slice from the cut challah. Be careful not to talk until the first bite of bread is swallowed. Everyone who is given a piece of challah from the person who said the bracha, should wait to eat his piece until after the one who said the bracha, eats his first bite.
